Buzz around Apple Pay is doing little to boost consumer interest in using smartphones to buy goods and services, a new poll shows.

Almost two-thirds, or 64 percent, of Americans say they'd "never" or "hardly ever" use their cellphone to make a purchase, according to a CreditCards.com report released Tuesday.

Those results are little changed from six months ago, when 62 percent expressed little interest in using their smartphones to make a transaction.

The results suggest that the public remains skeptical of services like Apple Pay, which was unveiled in September. Apply Pay is an app that stores credit card information.

"The biggest obstacles to mobile payments usage are convenience and security," said Matt Schulz, CreditCards.com senior industry analyst. Consumers are already comfortable swiping their credit and debit cards. "Most people don't see why a mobile payments service would be quicker, easier or more secure."

Just 6 percent of respondents in the CreditCards.com survey said they'd "always" make a mobile payment, and 11 percent would do so "most of the time."

When the same question was asked in September, a combined 13 percent of those answering responded similarly.

Interest in mobile payments is spread evenly through people of different income and education levels, CreditCards.com said.

The most likely to use mobile payments are Hispanics, millennials and Southerners, CreditCards.com said.

The least likely are whites, senior citizens and Westerners, said CreditCards.com, a credit card comparison website.

Of respondents ages 18 to 29, a quarter, or 24 percent, said they wanted to pay by phone always or most of the time. That figure dropped in older age categories, bottoming out at 8 percent of respondents ages 65 and up

The survey was conducted by Princeton Survey Research Associates International. It did landline and cellphone interviews in English and Spanish from Thursday to Saturday with 1,000 U.S. adults living in the continental United States. The margin of error is plus or minus 3.6 percentage points.
